Three Huffman High School students have been suspended for beating up a bus driver a few minutes after school let out Friday, school officials said.

Michaelle Chapman, spokeswoman for Birmingham city schools, said the incident was reported to her this way: The bus driver was standing outside the bus ushering students in. One male student was "straggling," she said, and the bus driver asked him to hurry up and get on the bus.

"He apparently got upset and slapped the bus driver," Chapman said. "The bus driver held him to keep from getting hit again."

At that point, two other students who were on the bus got off the bus and hit the bus driver in the head, she said.

School officials witnessed the altercation and took the three students into the building while a new bus was called in to take the remaining students home for the day.

"There were no visible injuries," Chapman said of the bus driver. Police were called to the scene, but Chapman said she doesn't know whether the students were arrested. They will, however, be suspended but Chapman said she didn't know how long the suspension will last.

"It was Friday afternoon after school, so the paper work probably won't be finished until Monday morning," she said.
